"If you only knew the magnificence of the 3, 6 and 9, then you would have a key to the universe."Nikola Tesla (source of this quote unknown which puts in question whether Tesla even said this). [See Keely references to 3 6 and 9]

I have found no other reference to this quote attributed to Nikola Tesla. Are there any? If you know the source of this quote and/or have more Tesla materials on this idea please contact me.
